Definitions
- the invention relates to a circuit card configuration according to the preamble of claim 1.
- An electric filter is usually made up of a circuit card with incoming and outgoing signals and connection to chassis ground.
- a problem with such filters by connection of coarse cable clips is that rigid cables result in breaking forces in the circuit card, wherein the laminate of the circuit card breaks due to the forces provided by the tightening torque.
- the casing of such a filter shall fulfil high demands on tightness and keep all parts in place during vibrations and impacts. Further it is desired that the filter is connected to chassis ground with low impedance.
- Screw caps or connectors are used to seal around incoming and outgoing signals and an earth braid or the like is then used to connect the circuit card to the chassis. Alternatively the card is grounded through its assembly spacers which results in many contact surfaces with contact resistance.
- US2003067751 shows a housing for an electronic control unit for a vehicle with an inner housing in plastic with corner-supporting metallic pin bolts and a metallic outer box. The metallic pin bolts are arranged to be pressed through corresponding openings in a circuit card until a step bears against its surface. Through this technique a mechanically robust and electrically conductive connection between the circuit card and the pin bolts is obtained.
- An object of the present invention is to provide a circuit card configuration facilitating simplified manufacturing, having few components, being cost efficient, facilitating good ground connection and being environmentally durable.
- circuit card configuration which is of the type stated by way of introduction and which in addition exhibits the features recited in the characterising clause of the appended claim 1.
- Preferred embodiments of the circuit card configuration are defined in appended dependent claims 2-10.
- a circuit card configuration comprising a card element being arranged to be attached via assembly points and to support connection points for signal connection and ground connection, wherein the respective assembly points as well as the respective connection points comprise a metallic bushing arranged to be attached at the card element.

- connection points direct connection to ground in e.g. a vehicles chassis wherein low impedance, i.e. low contact resistance is obtained, at the same time as the connection points may constitute assembly points.
- said metallic bushing is essentially made of brass.
- said bushing is arranged to be attached to the card element with soldered joints and/or screw joints.
- Soldered joints results in rational manufacturing of the filter. Soldered joints results in low contact resistance which is not impaired with time. By using screw joint removal of bushing is facilitated. Further a strong joint is facilitated.
- the card element with its bushings is arranged to be embedded in a cast compound.
- a cast compound the bushings are prevented from being turned and where applicable, i.e. where soldered joints are used, protects the soldered seam.
- the cast compound provides stability such that the card element/circuit card configuration withstands load from e.g. rigid cables, vibrations and the like.
- the cast compound improves the structural strength of the circuit card configuration. Further the environment durability is improved.
- said metallic bushing comprises a portion with a polygonal cross section. Said portion with a polygonal cross section further contributes to preventing turn of bushing when it is arranged in a cast compound.
- said polygon is a regular hexagon.
- screwing of the bushings by means of e.g. an adjustable wrench is also facilitated.
- said metallic bushing comprises an internal thread.
- said metallic bushing comprises a through hole for said assembly and/or signal connection. This simplifies assembly and facilitates signal connection. Hereby reduced torsion stress of soldered joints is facilitated by using screw joints with jam nut such that the card element is not used as a holder-on but instead the jam nut.
- said card element and at least parts of said bushings are housed in a box.
- structural strength of the circuit card configuration is further improved wherein a more robust construction is obtained.
- the box when cast compound is used, keeps the cast compound in place during the hardening process, the box may also be utilised as casting mould and subsequently be removed.
